NCLEX RN Predictor Exam
1. In the Gram Stain procedure, which component acts as the mordant?
- A. Crystal violet
- B. Methyl alcohol
- C. Iodine
- D. Safranin
Correct answer: C
Rationale: In the Gram Stain procedure, the mordant is Gram's Iodine. The purpose of the mordant is to form a complex with the crystal violet, enhancing its ability to bind to the cell wall. Crystal violet is actually the primary stain used in the Gram Stain procedure to initially color all cells. Methyl alcohol is the decolorizer that removes the crystal violet from certain cell types. Safranin is the counterstain used to stain those cells that did not retain the crystal violet stain after the decolorization step.
2. A client is receiving high-dose brachytherapy as a form of cancer treatment. What type of teaching must the nurse include when educating this client about safety?
- A. The client must remain in isolation under airborne precautions
- B. The client should stay in a private room at the hospital
- C. The client may need to limit visits from friends and family
- D. Both B and C
Correct answer: D
Rationale: A client undergoing high-dose brachytherapy has a radiation implant placed for cancer treatment. To ensure safety, the client should be in a private hospital room to prevent radiation exposure to others. Limiting visits from friends and family is necessary to prevent overexposure. Option A is incorrect as isolation under airborne precautions is not required for brachytherapy. Option B and C are the correct choices as they focus on minimizing radiation exposure to others, ensuring safety during treatment.
3. The abbreviation ac is defined as _____________.
- A. before the meal
- B. with the meal
- C. after the meal
- D. ante cibum
Correct answer: A
Rationale: The correct answer is 'before the meal.' The abbreviation 'ac' is derived from the Latin term 'ante cibum,' which translates to 'before a meal.' Choices B, C, and D are incorrect because 'ac' does not refer to 'with the meal,' 'after the meal,' or 'ante corpis.' It specifically denotes something occurring before a meal, making option A the correct choice in this context.
4. Which of the following scenarios provides an example of a healthcare professional overcoming a barrier to communication?
- A. A healthcare professional uses a visual aid to explain how to conduct a fingerstick glucose test to a patient with visual impairment.
- B. A healthcare professional writes down instructions for a patient who is hearing impaired.
- C. A healthcare professional raises their voice when speaking to a patient who does not speak English.
- D. A healthcare professional uses medical jargon while conversing with a minor.
Correct answer: B
Rationale: Overcoming barriers to communication in healthcare involves utilizing methods of communication that are accessible and understandable to the recipient. In the scenario provided, writing down instructions for a patient who is hearing impaired is an effective way to ensure clear communication and overcome the obstacle of hearing impairment. This method allows the patient to visually comprehend the information provided. Choice A is incorrect because using a visual aid for a visually impaired patient, not a hearing-impaired patient, would be more appropriate. Choice C is incorrect as raising one's voice does not address the language barrier effectively and may not enhance understanding. Choice D is incorrect as using complex medical terms with a minor may lead to confusion and hinder effective communication.
5. The most accurate reading for a temperature is done:
- A. Orally
- B. Aurally through a clean canal
- C. Rectally
- D. Axially
Correct answer: B
Rationale: Aural readings are done through the ear canal. The tympanic membrane shares a blood supply with the hypothalamus, the brain area that regulates body temperature. Taking the temperature aurally through a clean canal ensures an accurate reading. Choice A (Orally) is not the most accurate method for temperature measurement as it can be affected by external factors like drinking hot or cold liquids. Choice C (Rectally) is invasive and less practical for routine temperature monitoring. Choice D (Axially) is not a standard method for temperature measurement and may not provide accurate results.
